If you notice your Noom icon is missing from your iPhone’s home screen but it says Open when you go to the App Store, then the app is still installed on your device. It’s possible to hide icons from your Home screen, so it’s likely just stored in your App Library and you only need to place it back on the Home screen.
To see the Noom icon on your iPhone home screen again:
- With your iPhone unlocked, keep swiping left on the iPhone Home screen until it reveals the App Library.
- Find the Noom icon, long-press the icon, and tap Add to Home Screen to put the icon back on your iPhone’s home screen.
- Close the App Library and you should now see the Noom icon back with the rest of your icons.
